[BINUTILS, AArch64, 2/2] Update Store Allocation Tag instructions
This patch updates the Store allocation tags instructions in Armv8.5-A Memory Tagging Extension. This is part of the changes that have been introduced recently in the 00bet10 release All of these instructions have an updated register operand (Xt -> <Xt|SP>) - STG <Xt|SP>, [<Xn|SP>, #<simm>] - STG <Xt|SP>, [<Xn|SP>, #<simm>]! - STG <Xt|SP>, [<Xn|SP>], #<simm> - STZG <Xt|SP>, [<Xn|SP>, #<simm>] - STZG <Xt|SP>, [<Xn|SP>, #<simm>]! - STZG <Xt|SP>, [<Xn|SP>], #<simm> - ST2G <Xt|SP>, [<Xn|SP>, #<simm>] - ST2G <Xt|SP>, [<Xn|SP>, #<simm>]! - ST2G <Xt|SP>, [<Xn|SP>], #<simm> - STZ2G <Xt|SP>, [<Xn|SP>, #<simm>] - STZ2G <Xt|SP>, [<Xn|SP>, #<simm>]! - STZ2G <Xt|SP>, [<Xn|SP>], #<simm> In order to accept <Rt|SP> a new operand type Rt_SP is introduced which has the same field as FLD_Rt but follows other semantics of Rn_SP. *** gas/ChangeLog *** 2019-04-11 Sudakshina Das <sudi.das@arm.com> * config/tc-aarch64.c (process_omitted_operand): Add case for AARCH64_OPND_Rt_SP. (parse_operands): Likewise. * testsuite/gas/aarch64/armv8_5-a-memtag.d: Update tests. * testsuite/gas/aarch64/armv8_5-a-memtag.s: Likewise. * testsuite/gas/aarch64/illegal-memtag.l: Likewise. * testsuite/gas/aarch64/illegal-memtag.s: Likewise. *** include/ChangeLog *** 2019-04-11 Sudakshina Das <sudi.das@arm.com> * opcode/aarch64.h (enum aarch64_opnd): Add AARCH64_OPND_Rt_SP. *** opcodes/ChangeLog *** 2019-04-11 Sudakshina Das <sudi.das@arm.com> * aarch64-opc.c (aarch64_print_operand): Add case for AARCH64_OPND_Rt_SP. (verify_constraints): Likewise. * aarch64-tbl.h (QL_LDST_AT): Update to add SP qualifier. (struct aarch64_opcode): Update stg, stzg, st2g, stz2g instructions to accept Rt|SP as first operand. (AARCH64_OPERANDS): Add new Rt_SP. * aarch64-asm-2.c: Regenerated. * aarch64-dis-2.c: Regenerated. * aarch64-opc-2.c: Regenerated.
